This thing is looking a lot like an upturned animal with it's stumpy feet in the air!
The "feet" are sandboxes on supports. Fiddly to assemble, there are cut-outs in the bottom of each part that I don't think should be there as the sand would leak out. Worse, they weaken the soldered joints.
Much of the detail has been attached with solder paste and a RSU. I like using the resistance tool and should do more with it. The paste is less fun as the leftover, on this uncleaned model, is dark grey and not a pretty silver.
Lost wax details are a nice touch but they really need to be polished in some way after fitting. I have a small sandblaster that I'll use on this to see if I can clean the solder and cast brass surfaces.
